CHARLES FRANKLIN, OF LEIPSIG, OHIO.

' GRAIN-PUBIEIER. j

To all whomtrma'y concern: .Be it known that I, CHARLES W. FRANK- LIN, citizen of the United States, residing at 'Leigsic, in the county of Putnam and State I of bio,

have invented certain new and useful Improvements in Grain- Purifiers, of

which the following is a specification.

This invention is a grain purifier, for the purpose of purifying grain, and includes a device for purifying, scouring or cleaning the same. The grain is first run through a drier, and is then runpthrough the purifier, in order to produce'the desired result.

' In the accompanying drawings,Figure 1 is a vertical section of the purifier or cleaner; Fig.2 is a section on the line 5'-5 of igvpurifier'or cleaner comprises an uprighftf fresh air box 21, and an upright exhaiis't' box 22 for the foul air and waste.

Between these two boxes is a vertical grain box or chute 23, havlng a series of reversed screen shelves 24 and 25' arranged-so that the grain will naturally run from one to 25 the other and will be spread over the same,

it to roll and turn back and forth causin' until 1b,!BEICh6S the outlet at the-bottom. The grain is fed at the top of the grain box throughfa spent 28. The partition 33 between the fresh air box 21 and 'the grain box 23 has a series of openings from the top of which deflector plates 32 extend do\vn-' wardlyand outwardly at such an angle as to gather up and deflect the air diagonally 35 across the grain box. The partition 34; be

tween the waste box '22 and the grain box has a-seriesof air outlet openings from the bottom of which openings deflector plates 31 extend upwardly and outwardly at such 4 an angle that the foul. air is deflected upwardly as it enters the waste box 22,thus

giving the broken and light grain a chance to drop downwardly into said box in the bottom of which it collects. The grain box has an outlet at the bottom indicated at 27.

The foul air box has an outlet spout 26 at the bottom to. collect and save broken and light grainin the form of heavy screenings. The grain box 3 has an outlet 29 at the top for foul air and dust, and the foulair box Specification of Letters Patent. Application filed July 9, 908. Serial No, 442,654.

Patented Apr. 4, 1911.

22 has an outlet 30 at the top for the same purpose.

The fresh air box 21 tapers toward the top so as to make the pressure even, and receives the air under pressure-at the bottom from a fan 40..

The zig-zag arrangement of the perforated shelves in the grain box causes a flow of grain in a sheet from one to the other, and the air forced into the fresh air box enters through the openings in the partition 33 and is forced upwardly through the screen shelves, carrying'with it dust and dirt I and forcing the same out through the openings in the partition 34 into the exhaust or foul air box. This box is of large capacity,- so as to let the heavy screenings and grain settle-to the bottom of the box whereby all values are saved, the foul air and dust passing out at the top. The inlet and out-let openings in the opposite side of the grain box are so arranged that the air entering one inlet must pass up through several shelves before reaching the next outlet, and this prevents any heavy grain being blown out into the foul air box.

By running the grain first through a drier and then through the purifier, it' will be effectively dried, scoured, cooled, and cleaned, and no machinery is required except the fans referred to, and the apparatus will be found very useful in mills, elevators,

and the like, for the purpose of treating and preparing grain for market.

I claim:

A grain purifier comprising an elongated vertical box having a series of angular screens placed'iu zigzag relation one above the other to cause a flow of grain downwardly through the series in alternately oppositc directions, said box having also an inlet for grain and a separate outlet for foul air at its top and an outlet for grain at its bottom, a fresh-air box extending up one' side of the grain box, and a foul air box extending up on the opposite side thereof, the inner walls of said fresh and foul air boxes being provided with openings to admit fresh air to the grain box, and to permit the escape of foul air therefrom, each outlet opening being located a distance above the eon'esponding inlet opening, equal to several deflect the air upwardly as it enters the of said grain screens, deflector plates extendlatter. h I

ihg downwardly and outwardly. from the Intestimony Whereof,'I aflix my signature top of the inlet openings into the fresh air in presence of two itnesses.

5 box to deflect the air diagonally across the CHARLES W. FRANKLIN. grain box, and'deflector plates extending up- Witnesses: wardlyand outwardly from the bottom of A. A. SLAY'BAUGH,

the outlet openings into the foul air box to GEORGE R. PLACE.
